How to detect semantic only blockers vs. emit blockers

[basarat]

Previously we had:

success : output.emitOutputStatus === ts.EmitReturnStatus.Succeeded;
emitOnly: !success && outputFiles.length

Now getEmitOutput only returns :

interface EmitOutput {
    outputFiles: OutputFile[];
    emitSkipped: boolean;
}

With only emitSkipped we don't know if it was a complete success i.e. a semantically valid emit or just a bland best attempt emit.

Somewhat unfortunately, we don't have the distinction between syntactic and semantic errors in the compiler anymore.

@DanielRosenwasser would be great if you can look at #2290
